Damage assessment in Atata Island, Kolovao district, Tongatapu division, Tonga as of 18 January 2022
Map showing reefs with in the different Impact Zones.
The study was a remarkably productive and enriching experience for all who were involved. It became a forum for critical reflections and analysis. It also built a knowledge and understanding amongst different communities, villages and the survey team.

Access to safe drinking water is a basic need and is one of the most important contributors to public health and to the economic health of communities. Pacific island countries have yet to overcome the challenge of providing a safe and adequate supply of drinking water to its populations. Infectious, waterborne diseases, such as Typhoid and Cholera and newly emerging pathogens are a major cause of morbidity and mortality within the Pacific region.
An analysis is made of the groundwater resources of Tongatapu Island. The Ghyben-Herzberg approximation is used to estimate thicknesses of a fresh-water lens floating on seawater. Finite-difference calculations are used to estimate rainfall recharge rates, and calculations are made to investigate the dispersion of chloride ions across the fresh-water-sale-water interface. These calculations suggest that artificial recharge might be useful devise to control chloride concentrations in the fresh-water aquifier.
The Protected Areas Working Group (PAWG) of the Pacific Islands Round Table for Nature Conservation recommended a forum to better connect a diverse range of people and their work relating to protected and conserved areas. To increase efficacy with respect to gaining momentum with communications and conservation work, the Pacific Islands Protected Area Portal (PIPAP) was launched.
